Question

Hibernate and Postgres blob problem

Asked by: szczecin

I am currently rewriting my entity beans from 2.1 to 3.0 version. I do it with Netbeans J2EE project, the stuff is generated from datasource. Everything goes nice until I try to use (stacktrace in code section).

I assume it is problem of 'text' field from Postgres, my table contains. I have read there was a problem with Hibernate & Postgres - blobs were converted into big objects etc. But it was a bug from 2003 or 2005! And also I have been using this combo for last 3 years without problems. The only change I made is EJB, 2.1 to 3.0.

This is my persistence.xml:

<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
  <persistence-unit name="CustomerAccountPU" transaction-type="JTA">
    <jta-data-source>PostgresDS</jta-data-source>
    <properties/>
  </persistence-unit>
</persistence>

And postgresDS is exactly the same I've used for last 3 years:

<datasources>
<local-tx-datasource>
<jndi-name>PostgresDS</jndi-name>
<use-java-context>false</use-java-context>
<connection-url>jdbc:postgresql://192.168.1.106:5432/mydb</connection-url>
<driver-class>org.postgresql.jdbc3.Jdbc3PoolingDataSource</driver-class>
<user-name>user</user-name>
<password>password</password>
<transaction-isolation>TRANSACTION_SERIALIZABLE</transaction-isolation>
</local-tx-datasource>
</datasources>


My configuration is: JBoss 4.2.3 with EJB3 + Postgresql 8. I test my new beans inside Seam project - maybe this matters as well.

What should I change then?

I have done it by changing annotation in my entity bean class. One of the fields was byte[] in database, NetBeans during generation of bean from datasource marked this filed with annotation @Lob so it's being treated as Large Object. Removing this annotation helped for now.
